Last updated: April 2026 · Pricing verified from live Shopify App Store listings on April 22, 2026. Reviewed by the Libautech team, builders of Bundles & Upsell — a Built for Shopify popup upsell and bundle app used by 5,000+ merchants across 50+ countries.
Popups earned a bad reputation from intrusive, irrelevant interruptions in the early 2010s. What converted them from nuisance to conversion tool is targeting. A popup that fires immediately when someone lands on a homepage is disruptive. A popup that fires when a customer has spent 45 seconds on a product page, scrolled 70%, and is moving their cursor toward the browser tab is useful — it catches a qualified browser at the moment of decision.
There are two fundamentally different jobs a popup can do on a Shopify store, and most roundups make the mistake of comparing them as if they competed. They do not. An email-capture popup collects a contact in exchange for a discount. A cart upsell popup adds a product to the order at the moment of highest purchase intent. The first grows your subscriber list; the second grows your AOV in the same session. The best Shopify stores run one of each, not two of the same kind.
This post ranks 8 Shopify popup apps across both categories based on verified April 2026 pricing, Shopify App Store ratings, and what each app actually does beyond the obvious.
Popup strategy layers well with other conversion tools. See our guides on best Shopify SMS marketing apps for dual email and SMS capture, best cart drawer upsell apps for revenue-capture mechanics that pair with upsell popups, and best quantity break apps for tiered offers that work inside popup formats.

Best for: merchants who want popups to increase order value at the moment of purchase intent — cart upsell popups and post-purchase one-click offers — as part of a full AOV stack including bundles, FBT, and cart drawer upsells under one subscription.
Every other app on this list uses popups to capture email addresses. Libautech Bundles & Upsell uses popups to capture revenue. When a customer clicks Add to Cart, Libautech fires an upsell popup immediately — a targeted offer for a complementary product or an upgrade, shown at the single highest-intent moment in the shopping journey. The customer has already decided to buy. The question the popup answers is how much they will spend.
This is the add-to-cart popup mechanic that Shopify merchants have used for years to lift average order value. Libautech handles it inside a full AOV optimization platform — the same app that runs product bundles, volume discounts, Frequently Bought Together, cart drawer upsells, and post-purchase one-click offers also triggers the cart upsell popup. No separate app required, no conflicts between tools, no widget overlap on mobile.
The popup logic is product-aware: you define which products trigger which offers, and the app shows only offers relevant to what is in the cart. A customer adding a camera is offered a lens or memory card — not a random recommendation. That relevance is what separates a useful upsell popup from a disruptive one. Post-purchase popup upsells fire on the thank-you page with saved payment details, giving the customer a one-click add with zero friction.
Libautech Bundles & Upsell is Built for Shopify certified — it meets Shopify's highest standards for performance, reliability, and design. 5.0-star rating across 36 reviews. Widgets load asynchronously with no page-speed impact.
Where it falls short: the popup here is a revenue tool, not a list-building tool. If the goal is growing an email list, you need one of the other apps on this list in parallel (popups from both categories run fine side-by-side because they fire at different funnel moments). With 36 reviews the social-proof base is smaller than the category leaders by review count, though the Built for Shopify badge and 5.0 rating balance this for stores prioritizing quality over review volume.

Pricing: 7-day free trial. Starter $14.99/mo, Pro $29.99/mo, Unlimited $49.99/mo.
Best for: stores that want the deepest multi-condition targeting and the largest template library for email and SMS capture popups.
OptiMonk holds 4.8 stars across 980+ reviews and has the deepest targeting logic of any email-capture popup app on this list. Conditions can be combined in any combination: visitor is from a specific UTM source, has visited more than 3 times, has a cart value above $60, is on a specific product page, and has not seen this popup in the last 7 days. These layered rules let you show highly relevant offers to highly specific visitor segments rather than applying one popup to all traffic.
The template library has 300+ designs covering email capture, cart abandonment, product recommendations inside the popup, countdown timers, and gamified spin-to-win formats. The AI builder creates on-brand popups from a prompt in under a minute, and the drag-and-drop editor requires no design skills. A/B testing is available on all paid plans, and dynamic product recommendations can appear inside a popup from the free plan.
Where it falls short: not a native email platform. Popups capture contacts but you need a separate email tool (Klaviyo, Omnisend, Privy) to send welcome flows and campaigns. Some merchants have flagged usage-based pricing surprises at scale — verify your projected traffic tier before committing.
Pricing: Free plan available. Paid from $39/mo.
Best for: stores that want popup email capture plus basic email and SMS marketing in one tool without subscribing to a separate platform.
Privy is the most battle-tested option in this category with 4.5 stars across 4,100+ Shopify App Store reviews and nearly a decade of continuous use on live stores. It started as a popup tool and expanded into a lightweight email and SMS platform. The combination means a subscriber captured via a Privy popup flows directly into a Privy welcome sequence without exporting lists or connecting integrations. For stores not running Klaviyo or Omnisend yet, this consolidates two tools into one subscription.
Targeting covers exit intent, time on page, scroll depth, cart value threshold, and page-specific rules. A/B testing lets you compare offers, headlines, and designs. Over 100 pre-built templates cover email capture, spin-to-win, free shipping bars, and cart cross-sells. The platform also handles SMS subscriber growth through dual-capture popups.
Where it falls short: the built-in email marketing is lighter than Klaviyo or Omnisend. Stores already running or planning to run a dedicated email platform get more value from OptiMonk or Klaviyo Forms, since Privy's email features become redundant. Usage-based pricing on contact volume has also drawn merchant feedback about unexpected charges — review your tier carefully.
Pricing: Free plan available. Paid from $30/mo.
Best for: stores already on Klaviyo who want popups feeding directly into Klaviyo email flows with zero integration overhead.
Klaviyo Forms is the popup and form builder built into the Klaviyo platform. For stores already running Klaviyo for email, using Klaviyo Forms means a subscriber captured via a welcome popup automatically enters the Klaviyo welcome email flow in real time. No integration, no export, no sync delay — the popup is part of the same system as the subsequent emails and segmentation.
The form builder covers popups, flyouts, embeds, and full-page landing forms. Targeting uses Klaviyo's existing segment and property data — you can show a popup only to customers who have not yet subscribed to SMS, or only to customers who have placed one order in the last 60 days. A/B testing runs across form designs, timing rules, and offer variants. Dual email and SMS capture is native.
Where it falls short: if you are not on Klaviyo, there is no reason to use Klaviyo Forms specifically. OptiMonk, Privy, or Omnisend are stronger standalone popup tools. Klaviyo Forms earns its place only within the Klaviyo stack where the integration eliminates friction.
Pricing: Included in Klaviyo plans from $45/mo (email) or $60/mo (email + SMS).
Best for: stores that want popups, email, and SMS subscriber capture from a single platform subscription.
Omnisend (4.8 stars, 6,200+ reviews) is one of the highest-rated Shopify email platforms, and its popup and form builder is bundled alongside its email and SMS tools. A popup can capture both email and phone number simultaneously, adding the subscriber to email automations and SMS flows in one step. The subscriber growth tools — popups, landing pages, spin-to-win wheels, and embedded forms — all feed the same contact database that runs campaigns.
For stores running or planning to run Omnisend for email and SMS, using Omnisend's popup tools eliminates any separate popup app. The forms are functional and well-designed. Targeting covers exit intent, scroll depth, and time delay with straightforward configuration. Pricing starts at $16/mo, which is the lowest paid tier of any email-capable platform on this list.
Where it falls short: targeting sophistication is not as deep as OptiMonk or Wisepops. Stores that need complex multi-condition rules get more flexibility from dedicated popup tools. A/B testing is more limited than the pure popup specialists.
Pricing: Free plan available. Included in Omnisend plans from $16/mo.
Best for: agencies and mid-market merchants who want custom CSS control, AI-assisted popup building, and detailed per-campaign analytics.
Wisepops is positioned for more technical users. The custom CSS and HTML access lets you build popups that match any brand exactly — not selecting from preset color options but writing actual styles. Mobile-specific design mode lets you build separate popup layouts for desktop and mobile rather than scaling one design responsively. The AI popup builder creates on-brand campaigns from a short prompt.
The analytics dashboard tracks impressions, views, submissions, and conversion rates per campaign with more detail than most alternatives. For agencies managing client stores, the multi-site management features and granular per-campaign reporting justify the higher price point. The 4.9-star Shopify App Store rating is among the highest in the category, though review volume is smaller (68) than the established players.
Where it falls short: no free plan, higher starting price than most competitors. For solo merchants or smaller stores, OptiMonk provides comparable targeting and a better value proposition at a lower price. The smaller review base also means less long-term public track record than Privy or Omnisend.
Pricing: Free trial available. Paid from $49/mo.
Best for: stores that want strong Shopify-specific targeting — cart value, customer tags, order history — at a lower price point than the category leaders.
Poptin holds 4.9 stars across 303 reviews — one of the strongest ratings-to-volume ratios on the Shopify App Store. It focuses on lead capture and exit-intent popups with Shopify-native targeting: cart value thresholds, specific customer tags, order history, and product-page rules work out of the box without custom configuration. The $20/mo starting tier is below every other email-capture popup on this list except Omnisend, making it the budget-friendly pick for stores wanting real targeting without paying for broader marketing platforms.
Features cover exit-intent popups, spin-to-win, inline forms, surveys, and autoresponders. The popup builder is drag-and-drop with a strong template library. Mobile support is solid, and the integration list covers every major email platform.
Where it falls short: one Shopify reviewer reported popups continued appearing after the app was uninstalled — worth testing thoroughly before committing. Smaller feature surface than OptiMonk or Privy at the upper tiers. Pure popup tool with no native email marketing.
Pricing: Free plan available. Paid from $20/mo.
Best for: stores that want AI-powered product recommendation popups that show relevant products rather than just discount offers.
Justuno's differentiator is AI-driven commerce promotions. Beyond standard email capture, it displays popups that recommend specific products to a visitor based on browsing behavior, purchase history, and cart contents. A visitor browsing running shoes who is about to leave sees a popup featuring running accessories they have not viewed — a conversion prompt rather than a generic discount offer.
This product recommendation capability turns the exit-intent popup from a last-ditch email capture into an active merchandising tool. A/B testing, advanced segmentation, and the full range of standard popup types are all included. The integration list connects to every major email platform.
Where it falls short: no permanent free plan. The $39/mo starting price matches OptiMonk for broadly similar targeting features. Justuno earns that price primarily through the product recommendation engine — if you are not using that feature, OptiMonk or Privy deliver comparable value cheaper.
Pricing: 14-day free trial. From $39/mo.
Best for popup upsells, cart popup offers, and post-purchase one-click revenue capture: Libautech Bundles & Upsell. The only app on this list where the popup fires at purchase intent rather than page arrival, paired with bundles, FBT, and cart drawer upsells in one subscription at $14.99/mo Starter.
Best for email-capture targeting depth and template range: OptiMonk. 4.8 stars, 980+ reviews, 300+ templates, free plan, and the most sophisticated targeting logic in the category.
Best battle-tested popup + email combo: Privy. 4,100+ reviews, popup and email in one tool without a separate Klaviyo subscription.
Already on Klaviyo: Klaviyo Forms. Native integration with existing flows, zero connector overhead.
Popups, email, and SMS in one platform: Omnisend. Lowest starting price of any email-capable platform on this list at $16/mo.
Agency-grade popup design and analytics: Wisepops. Custom CSS, mobile-specific layouts, per-campaign reporting.
Budget-friendly Shopify-native targeting: Poptin. 4.9 stars, $20/mo, cart-aware and customer-tag-aware out of the box.
AI product recommendations inside popups: Justuno. Active merchandising at the exit-intent moment.
For most stores, the honest recommendation is to run two popup apps in parallel — one email-capture popup (OptiMonk or Privy feeding your email platform) and one cart upsell popup (Libautech Bundles & Upsell for AOV). These fire at different funnel stages and do not compete for the same visitor moment. Stores that try to do both jobs with a single app usually do both badly.
This ranking is based on four criteria applied to every Shopify popup app tested in 2026. First, Shopify App Store rating and verified review volume as of April 22, 2026 — the signal of long-term merchant satisfaction at scale. Second, pricing structure, specifically flat-rate versus usage-based versus contact-tier pricing (this determines total cost as the store scales, independent of the sticker price). Third, popup type and placement — email capture, dual email/SMS, or revenue capture at cart and post-purchase. Fourth, Built for Shopify certification and integration performance on live stores.

The best depends on what the popup is for. For revenue capture through cart upsells and post-purchase one-click offers, Libautech Bundles & Upsell is strongest because it combines popup upsells with bundles, FBT, and cart drawer upsells in one subscription. For email and SMS capture, OptiMonk leads with 4.8 stars across 980+ reviews and 300+ templates. Stores already on Klaviyo should use Klaviyo Forms. Stores wanting popup plus email in one tool should use Privy.
Email-capture popups (OptiMonk, Privy, Klaviyo Forms, Omnisend) collect subscriber contact info in exchange for a discount or content. They fire on page arrival, scroll depth, or exit intent, and their job is list growth. Upsell popups (Libautech Bundles & Upsell) fire at purchase-intent moments — when a customer clicks Add to Cart, reaches the cart page, or completes checkout — and show relevant product offers to increase order value in the same session. These are complementary, not competing. Most high-performing stores run one of each.
OptiMonk, Privy, Klaviyo Forms, Omnisend, and Poptin all offer free plans. OptiMonk's free plan gives the widest template library and deepest targeting. Privy's free plan is better if you also need basic email marketing in the same tool. Klaviyo Forms is free if you are already on Klaviyo for email. Omnisend is the best free starting point if you need email and SMS capture together. Libautech Bundles & Upsell offers a 7-day free trial rather than a permanent free plan.
Popups that block the majority of content on mobile can trigger Google's intrusive interstitial penalty, harming rankings. Modern popup apps like OptiMonk, Privy, and Klaviyo Forms comply with Google's guidelines by default — smaller formats on mobile, exit-intent triggers only on desktop, and respect for the first-visit grace period. Upsell popups from Libautech Bundles & Upsell are triggered by user action (Add to Cart or checkout completion) rather than passive page arrival, which falls outside Google's interstitial penalty entirely. Configure your popups properly and they do not hurt SEO.
For email capture, exit-intent popups with a clear offer (discount code, free shipping, early access) consistently convert at 3–8% of qualified exiting visitors. Gamified spin-to-win formats can convert higher on fashion, beauty, and gift stores (up to 15%) but can undermine premium brand positioning. For upsell popups, cart popup offers with a relevant product match and a small incentive (10% off, free shipping threshold, or a bundle discount) consistently convert at 8–15% attach rate. Test the format against your audience before committing.
Paid plans range from $14.99/mo (Libautech Bundles & Upsell Starter) and $16/mo (Omnisend) at the low end up to $49/mo (Wisepops) at the high end for standalone popup specialists. Klaviyo Forms is included in Klaviyo email plans from $45/mo. Usage-based apps (Privy contact tiers, Omnisend contact counts) can exceed $100/mo at scale — verify your projected volume before committing to a tier.
Yes. Omnisend, Klaviyo Forms, Privy, and OptiMonk all support dual-capture popups that collect email and phone number simultaneously. This is the most efficient subscriber growth format because customers who provide both channels are typically more engaged than single-channel subscribers. Always check SMS compliance rules (TCPA in the US, GDPR in the EU) before launching dual-capture popups.
All apps on this list have mobile-specific formats. Modern best practice: use smaller banner-style popups on mobile instead of full-screen overlays to avoid Google's interstitial penalty. OptiMonk and Wisepops have the most sophisticated mobile-specific design modes. Libautech's cart upsell popups are user-triggered and mobile-native by design. Always preview your popup on mobile before launching.
Yes — this is the setup most high-converting stores use. The two popup types fire at different funnel stages and do not interfere with each other. The email-capture popup runs before a product is in the cart (first visit, exit intent, scroll depth). The upsell popup runs after (Add to Cart click, cart drawer view, post-purchase thank-you page). Running both is how you grow your list and lift your AOV from the same traffic.
Apps with the Built for Shopify badge — including Libautech Bundles & Upsell — load widgets asynchronously, which means the popup logic appears after the main page content loads. This has no impact on core page speed or Lighthouse score. Non-certified apps vary in performance. Always check for the Built for Shopify certification before installing, and test page speed before and after activation.
